They take all of the fragmented pieces of files on your hard drive and consolidate them back into contiguous files. This can speed up performance since your computer doesn't have to search for the file fragments.
I would do defragmentation on it, check for a virus, and even reinstall programs.
Defragmentation. In Windows: Click: Start -> Programs -> Accessories -> System Tools -> Disk Defragmenter
Yes. All Windows based file systems require periodic defragmentation for optimal performance. FAT, FAT32 and NTFS file systems all require defragmentation.

To speed up your Fujitsu Lifebook, you can try uninstalling unused programs, disabling startup programs, increasing RAM, upgrading to a solid-state drive (SSD), and performing regular system maintenance such as disk cleanup and defragmentation.
Disk defragmentation helps to keep the HDD activity smooth and fast thus preventing lags in the opening of files, programs etc. Another important advantage is that if you defrag regularly, you dont need to wait for ages before your PC starts or shuts down. It contributes to maintaining good speed and performance of your system.
First try a disk cleanup and disk defragmentation. If that doesn't work type msconfig in the run box and eliminate any unneeded startup programs. If neither of those options work try deleting old programs that aren't used anymore.
Depends on the file system.
No. It is impossible for defragmentation software to remove anything from your computer. The only way that it could would be if you closed the defrag program while it was in the middle of working, and even then it shouldn't remove multiple games, maybe create a few missing files, but not remove them. If you are using Windows 10, I have heard a few rumors about how Microsoft can uninstall any pirated software on your computer. But no, it is impossible for a defragmentation program to remove good, working games, let alone any program.
Defragmentation :)
Defragmentation.
Use it regularly, as part of a scheduled maintenance program. Keeping your hard-drive de-fragmented will help your computer by keeping files, programs etc ordered on the disc. A good schedule is once a week.
